Because Dr. McNinja’s home, Cumberland, Maryland is in the Potomac Council! (Also, I’m an Eagle Scout from Potomac Council.) And it’s time they got some Jamboree patches that didn’t have a train, or the C&O Canal or like… the entrance to a very long tunnel on it or something.

If you’re interested in getting ahold of any of this set for yourself, (Top is the trader. Middle is the contingent patch. Bottom is the staff patch) you’re going to have to be attending the 2010 Boy Scout National Jamboree. Seek out members of Troop 420, or Jamboree Staff members from the Potomac Council. If you’re lucky, they’ll be willing to trade.
